Multi-speed bikes

As a highly versatile touring bike, the Bridge Club hits the sweet spot that separates on- and off-road excursions. The simplistic design makes it fully adept to handle a full rack and pannier setup, frame bags, or any combination of the two. It doesn’t feel sluggish on paved shortcuts, but can also hold its own on dirt detours. If you’re feeling a little zesty on your next road tour, you won’t be ill-prepared for reroutes through the woods. The Bridge Club is designed to handle it all. - 100% Surly Chromoly frame, main triangle is double-butted; 1-1/8" threadless Chromoly fork - Rack, fender, and four sets of three-pack mounts - Disc brake-specific, single-position vertical rear dropout makes it less intimidating than other bikes in the category - Clearance for 700 x 47mm (with or without fenders) or 27.5 x 2.8" tires (27.5 x 2.6" with fenders)

Steel Commuter and Gravel Bike Preamble is a hard-boiled steel commuter built for comfort, durability, and buffoonery on pavement and gravel. Nothing More is Needed. Nothing Less Will Do. The challenge was thus: Build a serious steel bike and give it only the attributes that matter most. Make it quick and comfortable on pavement, as well as confident and compliant on degraded surfaces. What the Enginerds put forth is Preamble, a pavement and gravel utility worker that proves you don't need to cut corners or clip coupons to make a more affordable steel bike. You just need to keep shit simple. Preamble can run racks and fenders and carry a couple water bottles. Surly was raised on stealing basic cable, after all. Smooth and efficient on asphalt, Preamble's double-butted main triangle provides a resplendent ride feel and withstands abuse from life's inevitable potholes. Make it your own with flat bars, drop bars, a basket, or bags. On the road to steel euphoria, Preamble is the gateway drug. Let facts be submitted to a candid world: - Offered in flat-bar and drop-bar configurations - Easy T-Shirt sizing to fit nearly every rider (XS, S, M, L, XL) - Sloping top tubes on XS and Small frames for improved standover and comfort - To offer the best rider experience for every frame size, XS and S frames get 650b wheelsets while M–XL get 700c - Custom-cast single-position vertical dropout

Straggler also handles our 8- and 24-Pack Racks well, so you have some heavier-duty loading options. - Accommodations for racks and fenders - Forward-exiting horizontal dropouts for singlespeed compatibility and wheelbase adjustability - Clearance for 700c x 41mm tires with fenders!

For those that love the idea of carrying gear with the assistance of an e-MTB the El Kahuna SUV is the answer! Like its sibling, the El Kahuna, the SUV features a sturdy aluminum frame and 29” wheels. The big differences are the addition of front and rear lights, and a rear rack which is integrated with a fender keeping you cleaner while you carry that camping gear up that big gravel road. A 100mm fork smooths out the bumps, and powerful disc brakes keep you in control while you rally around the campground’s gravel trails and singletrack.

The Unit X has become a cult favorite among die-hard Kona fans. Maybe it’s the Cromoly frame. Maybe it’s the fact that it’s a bikepacking monster, or its well-geared 12-speed drivetrain, or modular dropouts which give you the ability to run it as a single speed if that’s your thing. Maybe it’s because the rigid fork makes it that much more of a classic. We may never know why the Unit X is such a popular bike, but we can only guess it’s because it is one of the most practical machines in our lineup.
